摘要： Electronic component validation testing is facilitated by a method, system and program product which allows the importation of virtual signals derived from simulation verification testing of the electronic component design into electronic test equipment employed during validation testing of the actual electronic component. The method includes: storing simulation data resulting from simulation testing of an electronic component's design; employing electronic test equipment to perform real-time testing of the actual electronic component and obtain real-time test signals therefor; automatically correlating the stored simulation data with the actual real-time test signals; and performing at least one of overlaying and/or displaying the correlated simulation data as virtual signals with the real-time test signals; and employing a trigger event automatically ascertained from the stored simulation data and triggering the electronic test equipment based thereon, thereby automatically controlling real-time testing of the electronic component via the stored simulation data.

摘要： A methodology to perform testing of integrated circuits (IC) wherein a reduced number of Input/Output (IO) pins may used to load testing patterns and capture test results from test structures after an IC has been installed in its intended application is provided. This methodology utilizes a software engine that receives and translates a parallel test pattern into serial data patterns operable to be provided on the reduced number of I/O pins. A serial process loader then loads the serial data patterns to the test structures within the IC. The IC receives the serial patterns and in turn translates them into parallel test patterns in order to apply the test patterns to the appropriate test structures. The results are captured and then translated into a serial format for communication from the IC to a test unit for analysis.

摘要： Exemplary methods, apparatuses, and products are described for creating a behavioral model of a hardware device for use in a simulation environment. The behavioral model is created by an iterative process that includes receiving in a simulated hardware device from a simulated device under test (‘DUT’) a stimulus waveform. The stimulus waveform includes data representing a number of stimuli. In response to receiving the stimulus waveform, the simulated hardware device presents a recorded response waveform from a recorded response file to the DUT. The stimulus waveform is also recorded. The recorded stimulus waveform is presented to the hardware device. A response waveform that results from presenting the recorded stimulus waveform to the hardware device is recorded in the recorded response file.

摘要： A technique for spread-spectrum communication which uses more than one mode and more than one frequency band. Selectable modes include narrowband mode and spread-spectrum mode, or cellular mode and microcellular mode. Selectable frequency bands include both licensed and unlicensed frequency bands, particularly frequency bands including the 902-928 MHz, 1850-1990 MHz, and 2.4-2.4835 GHz frequency bands. Spread-spectrum communication channels are 10 MHz or less in width. The frequency band onto which spread-spectrum signals are encoded may be changed upon a change in environment or other control trigger, such as establishment or de-establishment of communication with a private access network.

摘要： A system for publishing data on shared broadcast channels using spread-spectrum techniques, which may comprise a spread-spectrum encoder capable of receiving data and placing it in a spread-spectrum signal format and a transmitter operating on a shared communication channel or frequency band, such as might be allocated to terrestrial point-to-point or broadcast communications. The shared communication channel may comprise a cellular system, in which data may be transmitted using spread-spectrum techniques using the transmitters and repeaters of the cellular system simultaneously with voice and other transmissions associated with the cellular system. A subscriber station may be capable of receiving using a plurality of different communication channels or frequency bands, such as a first receiver capable of cellular reception and a second receiver capable of satellite reception, at least one of which uses spread-spectrum techniques. The subscriber station may also comprise a transmitter using at least one communication channel or frequency band, so that the subscriber station may receive data or other transmissions using one channel and may request further data or other transmissions using a second channel.
